MAKE INVALID STATES UNREPRESENTABLE

Invalid states can lead to runtime errors and less reliable code. However, by shrinking the gap between representable, valid states, errors can be moved from runtime to compile time, which allows them to get caught much earlier. Type systems can and should be used to model business logic that makes invalid states impossible and unrepresentable. This article goes through a few examples, such as a “Color” type that prevents invalid colors.

US DEPARTMENT OF JUSTICE SEEKS 3-YEAR JAIL SENTENCE FOR FORMER BINANCE CEO CZ

The sentencing is scheduled for April 30th.

HOW LIGHT CAN VAPORIZE WATER WITHOUT THE NEED FOR HEAT

A team of researchers at MIT have demonstrated that light can cause water to evaporate in the absence of any source of heat. The discovery, named the photo molecular effect, could have significant implications in science and manufacturing. The effect happens widely in nature. It is strongest with green light that hits the water surface at a 45-degree angle with a certain type of polarization called transverse magnetic polarization.
